?Use 4.3-inch IPS TFT LCD and resistive touching screen, with a larger view angle and can be seen clearly in strong outdoor light.
?Switch to a large capacity 5000mAh/3.7V lithium battery, longer standby time, and expand a USB interface. Usually, it can be used as a power bank when the instrument is not used.
?The Lipo charing IC to be changed to IP5306 (with 2A high charing current), making the charging time shorter.
?Standard aluminium housing to protect SMAhead and reduce the interference of external electromagnetic wave to instrument. The NanoVNA-F measurement range is 50k-1GHz. Use the harmonic of the clock chip SI5351 to measure frequency up to 1000MHz. At 600M-1GHz, the S11 has a dynamic range of 40dB (the standing wave ratio is less than 1.02).
?The RF front end is designed with a metal shield that allows the S21 to have a dynamic range better than 60dB over the full frequency range.
